Steering Vibrate While braking.

Hello,
I have 05 Sienna. When I’m driving above 50 and hit the brakes my steering vibrate badly. Anyone has any idea what it’s about and what I have to do.:runaround:
Thanks,

possible warped front brake rotors

have the brake system checked if you didn't already pulled the wheels off and inspect the rotors and pads already...

Few months back the dealer inspected the bracks and they didn't find any problem in the pad and shoe. So if I again to the workshop, do I have tell speficly about the rotors or the brake inspection iclude rotors too.
Regards,

key word "possible"

did they made sure that the front rotors aren't warped by measuring with a dial gauge?

and if the rotors are also too "thin" they will start to warp as well...
------------------------------------
the dealer technician should have driven the vehicle at highway speeds & confirm your complaint; maybe let the service writer or technician ride along with you as a passenger and show him first hand...
------------------------------------

i assumed that the dealership also did a visiual check of your suspension/steering parts (joints/ bushings/axles/wheel bearings/etc.)

------------------------------------
I guess if everything physically checks out ok, maybe the ABS sensors-wiring-connectors-controller are bad somewhere, but this is still another "possible" cause
